MACHINE FOR MAKING WAISTBANDS, &.c.

SPECIFICATION forming part of Letters Patent No. 593,393, dated November9, I897.

' Application filed February 24,1897. Serial No. 624,880. (No modem To(0% whom it may concern.-

Be it known that I, HERMAN GREEN, a citizen of the United States,residing in the city and county of New York, in the State of New York,have invented certain new and useful Improvements in Machines forlWlakin g YVaistbands, &c., of which the following is a specification,reference being had to. the accompanying drawings, forming a partthereof.

This invention relates in general to machines for the manufacture ofwaistbands and other like articles in which tabs or loops are applied tothe body fabric; and the object which I have had in view is theprovision of means for applying such tabs or loops to such body fabricwhereby the manufacture of the waistbands or other articles may becarried on with great rapidity.

I prefer to employ my devices in connection with a sewing-machine ofsubstantially ordinary construction, and in accordance with my inventionI have provided a tab or loop holder, whereon the tabs or loops areplaced by the operator or by any suitable means, and which is caused totravel so as to apply the tabs or loops at the desired intervals to thebody fabric, which preferably passes immediately to the stitchingmechanism of the sewing-machine, by which the tabs or loops areimmediatelysecured to the body fabric. I have also provided means forfeeding the body fabric and means for severing the body fabric after thetabs or loops are attached thereto into lengths suitable for use.

The various features of my improved devices will be more fully describedand eX- plained hereinafter with reference to the accompanying drawings,in which I have illustrated a convenient and practical embodiment of myinvention.

In said drawings, Figure 1 is a front elevation of a sewing-machine ofordinary construction to which my improvements are applied. Fig. 2is aplan view of the same. Fig. 3 is an end elevation thereof, and Fig. 4 isa detail view to be referred to.

The sewing-machine to which my improvements may be applied may be of anyordinary construction. As represented in the drawings, it comprises abase or table A, having a clothplate a, arm B, shaft 0, with driving twoneedles cl d, presser-foot E, and footbar E, all as usual in machines ofthis description. For the special class of work for which this machineis intendednam'ely, the manufacture of waistbandsit may also be providedwith a folder F for the purpose of properly folding over the edge of thefabric and holding the fold open to receive the tabs or loops beforethey pass together beneath the 'presser-foot.

As a convenient means of driving the working parts of my devices Iprefer to provide on the shaft 0 a pinion c, which meshes with the gearG on a shaft G, which is supported by suitable bearing-standards'g g.The tab or loop holder H is adapted to receive the tabs or loops fromthe operator or from any suitable source and to present them insuccession to the body fabric. It will be obvious that this tab or loopholder may be arranged in many different ways, but I prefer that itshall have the shape of a wheel or disk which for convenience isdisposed in a horizontal plane, with slots or notches or other devices hh at intervals about its periphery, each one of which is adapted toreceive a single tab or loop and to deposit it upon the body fabric inadvance of the presser-foot. This disk orwheel which carries the tabs orloops may be securedto a vertical shaft II, which is supported insuitable bearings secured to the base A and the arm B and has securedthereto a worm-wheel hto be engaged and driven by a worm g on the shaftG. The proportions of the gears by which the holder or carrier H isdriven are preferably such that the peripheral speed of the holderorcarrier is substantially the same as the speed of travel of the fabricthrough the machine, but obviously the speed is not necessarily thesame. As indicated, the cloth-table a is preferably elevated somewhat,so that its upper surface shall be substantially in the plane of theloops or tabs as they are presented by the holder or carrier II, and thelatter is clear of the base to permit the fold of the fabric to I passunder the same. As the tabs or loops project from the edge of the holderor carrier and pass with the fabric and between its folds under thepresser-foot and are stitched upon the fabric by the stitching mechanismthey ing-pulley c, needle-bar D, preferably carry- 1 are drawn from theholder or carrier by'the fabric, leaving the slots or other holdingdevices h free to receive other tabs or loops.

It is desirable to provide devices additional to those which form a partof the ordinary sewing-machine for the purpose of feeding or drawing thefabric steadily through the machine,and for this purpose I have provideda pair of feed-rolls I I. The lower roll I has secured to its shaft agear 7;, which is engaged by an intermediate gear i driven by a pinion gon the shaft G, while the upper roll I has its bearings in movableblocks '6, for the adjustment of which screws t are provided, so thatthe pressure of the upper roll upon thelower-can be regulated. It willbe understood that the two rolls I I are operated continuously and drawthe fabric forward at a substantially uniform speed.

In order to prevent the possible breaking of the needles by the forwardmovement of the fabric when the needles are in it, I prefer to drive therolls yieldingly rather than positively, or, at least, so that the rollsmay give slightly if the fabric is held by the needles. A convenient andefficient device for this purpose is shown in Fig. 4E. The lower roll Iis loose upon its shaft I and has a recess 2' in which is placed aspring or cushion 1', preferably of rubber. A pin on the shaft I entersthe recess and drives the roll through the spring or cushion, therebypermitting the movement of the roll to be checked momentarily if thefabric is held by the needles.

Upon the supplemental table or extension A, which supports thefeed-rolls I I, is also supported a cutter which is operated at regularintervals to sever the successive lengths of the fabric after the tabsor loops have been secured thereto. As represented in the drawings, suchcutter may comprise an ordinary shear-knife K, which is pivoted at theend of the extension-table A. It may be operated by any suitable meanswhich will provide for its operation at the proper intervals. I haveshown it as having applied a spring 70, which maintains the bladenormally in its open position to permit the free passage of the fabric,and is adapted to be operated in the opposite direction by a lever K,which is pivoted to the extension A, and has at its inner end a roller Kto stand normally in the path of a cam h on the holder or carrier H,thus providing for the severing of the fabric after it has received thenumber of tabs or loops carried by said holder or carrier.

It is obvious that during the operation of the cutter the travel of thefabric betweenthe cutter and the feed-rolls I I is checked and that thefabric might wrinkle or pucker so that its end would not pass under thecutter when the cutter opens. It is therefore feed-rolls I and I and thecutter after each operation of the cutter. I have therefore provided apair of feed-rolls L L, the lower one of which is supported in fixedbearings and is driven by any convenient means, as}? by belt'and pulleysZ I from the shaft of theft? 5 roll I, the said roll L having a.somewhat greater peripheral speed than the roll I. The upper roll Lrests of its own weight or under spring-pressure on the lower roll L andis carried by a swinging frame or arms .M, one of said arms or one sideof said frame having an extension or finger 'm in the path of the leverK, so that when the latter is moved to operate the cutter it shall atthe same time lift the upper roll L from the lower-roll L and so stopthe feed of the fabric and allow it to accummulate between the two pairsof rolls.

To prevent the fabric from wrinkling or puckering between the rolls L Land the cut ter when the latter is closed, a guide-plate N is supportedabove but in close proximity to the table A, so as to leave a passagefor the free movement of the fabric While preventing its wrinkling orpuckering. The guideplate is preferably extended in front of the rolls LL, being slotted for the upper roll L, and has its end turned up. WVhenthe cutter has operated and is opened again, the roll L descends and thefabric is fed forward until it is straightened out between the two pairsof rolls, and thereafter the rolls L L slip upon the fabric, its normalspeed of movement being determined by the rolls I I.

It will be obvious that various changes in the construction andarrangement of the various parts herein shown and described may be madewithout departing from the spirit of my invention, and therefore I wishit to be understood that my invention is not to be limited to theprecise construction and arrangement of parts herein shown anddescribed.

I claim as my invention- 7 1.
